An introduction to the element of helium

Helium occurs in natural form as a gas it is a pure substance, ie an element in the periodic table one mole of helium atoms = 6022 x 10 23 helium atoms number of atoms in m moles = m x avagadro’s constant = m x 6022 x 10 23 so, 10 moles of helium (he) contains 10 x 6022 x 10 23 = 60022 x 10 23 helium atoms.
